Overview

Our client is a fast-growing RegTech startup using AI to transform how financial institutions approach AML and compliance workflows. They're hiring Full Stack Engineers to join a compact, fast-moving team working on two flagship products-an intelligent API for AML decision-making and an AI-driven report generation platform simulating the work of a financial crime analyst.

The company is venture-backed, with an active client base across fintechs and ambitions to break into large-scale enterprise. This is a unique opportunity to have end-to-end impact-designing, building, and deploying features in an environment where engineering best practices are respected and expected.

Key Responsibilities

  • Design and build scalable backend and frontend components for core products

  • Drive feature development from concept to deployment, working autonomously or in small teams
  • Collaborate with engineering leadership on technical direction and architectural decisions
  • Work on complex problems involving data aggregation, report generation, and AI agent integration
  • Contribute to product evolution based on customer feedback and internal roadmap

Ideal Candidate

  • 5-10 years' experience delivering production software in fast-paced environments
  • Comfortable working across backend and frontend (slight backend lean preferred)
  • Strong ownership mindset-able to ship features independently (build + deploy)
  • Experience managing multiple workstreams in low-management settings
  • Product-focused engineer who thrives in flat, startup-style team structures
  • Good grasp of engineering best practices, code quality, and system design

Tech Stack

  • Python
  • JavaScript / TypeScript
  • SQL
  • AWS (Cloud Infrastructure)

Interview Process

  1. Technical Discussion (30-60 mins)
  2. Collaborative Co-working Session (60-90 mins) - Solve a real-world problem together via screen share

Both stages are conducted remotely.
